Hair colorant: Indigo gives natural black colour to the hair and effectively covers gray hairs
Safe: Most hair dyes contain ammonia, ppd and other dangerous chemicals that can cause allergic reactions or can even cause cancer; Indigo is natural having no side effects
Conditioner: Indigo also works as a nice hair conditioner; So, you need not use a separate conditioner after using natural hair dye
Brown hair dye: When henna and indigo both applied to hair it gives lovely dark brown colour to the hairs
Black hair dye: When indigo and amla applied to hair it gives black hair colour; Amla is more as a hair nutrition-er than hair colour
